I get the same result with tip:
>>> import pyglet
>>> data = [1,2,3,4] * 10 * 10
>>> a = pyglet.image.ImageData(10, 10, 'RGBA', data)
>>> a.get_data('RGBA', 4)

I'm not really an expert in any of this, so I don't know best practices,
but this does seem sort of like bytearray() is the ideal type here. I'd
offer to work on a patch to do just that, but I'm not really 100% on the
details of ctypes and OpenGL, so I'm worried I might break more than I fix.

I created that ticket (I'm in the arduous process of moving to a different
email address :-). I just submitted a patch, but I'm not really sure it's
enough. Writing good programming guide docs is a lot harder than it looks.
Thanks,
